Abstract
A process for preparing pyrazine derivatives of formula-01 (I): ** (Formula-01) ** where R1 is phenyl substituted by halogen, alkoxy, alcohol, carboxyalkoyl, -NR4R5, carboxyl or alkoxycarbonyl, R3 is hydrogen, alcohol, mono- or di-carboxyalkoyl, halo, alkoxy, phenyl, halophenyl, hydroxyl, phenoxy, thiol, thioalkoxy, phenyl, halophenyl, hydroxyl, phenoxy, thiol, thioalkoxy, thiophenoxy, -NR4R5, cyano, -COOH, carboxyureide, -CF2, -COR6, hydroxyalkyl, aminoalkoxy, or alkoxy substituted by NR4R5, ring A is a benzene or pyridine ring optionally carrying up to 4 R3 substituents, which may be the same or different, R4 and R5, which may be the same or different, individually represent hydrogen, phenyl, halophenyl or alcohol.
